           Summary: LLVM+Clang fails to build when configured with
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: llvmbugs at contacts.eelis.net
                CC: llvmbugs at cs.uiuc.edu

When I try to build with

  ./configure --disable-threads

I get (after a while):

  llvm[4]: Linking Debug+Asserts executable clang
In function `llvm::sys::ThreadLocal<(anonymous
namespace)::CrashRecoveryContextImpl const>::erase()':
undefined reference to `llvm::sys::ThreadLocalImpl::removeInstance()'

Without --disable-threads it builds without problems. I also didn't have
problems building with --disable-threads a week or two ago, so it's probably a
recent commit that's to blame.

I'm using r111620.
